u/ChemicalFallOut

I've had my ears at a 0g for at least a year now. Last Sunday I went to a concert and changed them to a pair I have worn before, they were stainless steel and I've never had a problem with them before. I wore them a few days after the concert then noticed some pain, so I switched back to my silicone ones. Then the pain got worse and swelling started so I took them out. I don't understand what's going on?? It's not noticeably hot or warmer than my other, non effected stretched ear. The dark spot on the back feels like a scab.
